VEGETABLE KNIFE Filed March 27, 1929 Patented Feb. 17, 1931 PATENTOFFICE JACOB NORTI-ICUTT, OF LONG BEACH, CALIFORNIA VEGETABLE KNIFEApplication filed March 27, 1929. Serial No. 350,266.'

This invention relates to improvements in vegetable knives andparticularly to an at tachment adapted to be applied to a vegetableknife to facilitate its use. The invenlion may be considered as animprovement over the construction disclosed in my pending application,Serial No. 177,774, filed March 23, 1927.

An object of the present invention is to provide an improvedconstruction adapted to be applied to a vegetable knife which improvedconstruction is so constructed that it may be applied by slipping itlaterally on the blade of the knife so that it is applied over the edgeof the knife, forming a guide determining the thickness of peelingspeeled from vegetables by the knife.

Another object of the invention is to provide an attachment adapted tobe applied to 29 vegetable knives and the like which has a guide rolleradjustably mounted by an improved form of adjustment which willfacilitate adjusting the guide roller to vary the thickness of thepeelings or slices.

A further object of the invention is to provide an attachment forvegetable knives which provides for the application of a part enablingthe knife to cut a plurality of slices simultaneously from a vegetable.3O lVith the foregoing and other objects in view which will be mademanifest in the following detailed description and'specifically pointedout in the appended claims, reference is had to the accompanyingdrawings for an illustrative embodiment of the invention, wherein: p i iFig. 1 is a top plan view of a vegetable knife illustrating theattachment having been applied thereto.

Fig. 10 is a perspective View of the part adapted to be applied to thedevice in cutting the plurality of slices.

Referring to the accompanying drawings wherein similar referencecharacters designate similar parts throughout, the vegetable knife towhich the device is adapted to be applied may be of any conventionalconstruction. It is shown as having a blade 10 which is flat and has astraight cutting edge 11. The handle of the knife is indicated'at 12.The invention comprises a frame having a top bar 13 which is supportedby upright standards 14 and 15, the bottoms of which are bent laterallyand formed into U-shaped clamps 16 and 17. The clamps 16 and 17 are openat their rear ends so that the frame can be slipped laterally onto theblade 10 of the knife from the cutting edge 11. By the improvedconstruction it will be appreciated that the frame is applicable to anyconventional form of knife and that the shape of the blade may varywithout requiring variations in the construction of the frame .to enableits application.

Vertical slots 18 and 19 are formed in the standards or uprights 14 and15 forwardly of the top bar 13. As clearly shown in Fi 1:. 8 the slot 18has rear side serrated as indicated at 20 while the slot 19 has itsforward side serrated or notched as indicatedai indicated at 24: andthen bent downwardly as indicated at 25 and finally bent inwardly asindicated at 26. The inwardly bent ends 26 are offset with respect tothe pintle 22, i. e. the inwardly bent end 26 which is disposed with.-

in the slot'18 is offset rearwardly' with respect to the pintle so thatit bears against the serrated side 20 of the slot. In a similar mannerthe inwardly bent end 26 on. the end of the pintle 22 which is disposedin the slot 19 is offset forwardly with respect to the pintle so that itbears against the forward serrated side 21 of the slot. The edges of theinwardly bent ends 26 are preferably sharpened as shown in Fig. 6 sothat they will tit'into the notches or serrations in the sides of theirrespective slots. This construction serves to adjustably mount the guideroller 23 in the slots 18 and 19. To adjust the roller with respect tothe edge 11 of the knife blade 10 the inwardly bent ends 26 are pressedso as to bring them in alignment with the pintle 22 thus moving the ends26 out'of the notches and enabling the pintle and guide roller to bevertically shifted. On releasing the ends 26 they will imn'icdiatclyspring laterally and engage thei r respective notches in the sides oftheir respective slots.

By the improved construction it will. be noted that the guide roller canbe adjusted with respect to the knife edge 11 but at all times theroller is in parallel spaced relation to the knife edge and arrangedslightly forwardly of the knife edge. In using the knife the rollerrolls upon the exterior surface of the vegetable and serves to guide thecutting edge of the knife so that the knife blade will remove a peelingfrom the vegetable. By adjusting the roller the thickness of the peelingcan be varied and the knife can be advantageously employed in slicingvegetables.

The :drawing illustrates the roller :2 position so that if the userright h the stroke of the knife in peeling w toward the user. I fin d ti i position of the frame so c roller will be on that side of the bladeshown in Fig. that the knife can be stroked away from person of theuser. By using the device in this manner the knife can be strokedagainst the surfaceof the vegetable very quicl and caused to remove thepeeling-gs quite i y The improved construction enables the a plicationof an attaclnncnt shown in hi and 10. This attachnmnt comprises a base2i) having its forward edge tapered as indie) at 31 and having forwardlyextending 5i and 3 The outer side ed of the arms are tapered asindicated at 31 are adapt ed to slide inwardly into the Line between theblade 10 and the l ases v c Wards it and 15. The upstanding stops 35 atthe forward ends of the arms engage the forward edges of the standardsand limit the inward movement of the attaching part. On the base 30there are upstanding knives 36. the

upper ends of which have their backs cut away as indicated at 37 and arereceivable in'notches 38 formed in the top bar 13 on the frame.l'Vhenthis device is applied-the roller may or may not be removed. \Vhcna slice is cut by the knife blade ll from the vegetable the slice wi lpass rcarwardly until it cugages the knives 36 which cut the slice intorips.

From tl above described constriu-tion will be ajipirciated that anin'lprovcd vegetable knife attaclnnent provided which so constructedthat it may. he applied laterally across the cutting edge of anysuitable form of knife thus .i'naking the device universally applicable.The improved constrnction also has a novel adjustment of the rollerwhich enables the roller to be asily and quickly adjusted into anydesired position to vary the thickness of the peelings or slices cutfrom vegetables.

Various changes may be made in the details of construction withoutdeparting from the spiri or scope of the invention as defined by theappended claims.

I claim:

1. An attachment for vegetable knives comorising a frame attachable to aknife blade, said frame having a pair of slots formed therein. saidslots each having a serrated side. and guide means adjustable in theslots and having portions engageable upon the serrated sides.

2. An attachment for vegetable knives comprising frame attachable to aknife blade. said frame having a pair of slots formed therein, saidslots each having a scr rated side. a pintle extending through the slotsand having returned ends which are offset so as to bear against theserrated sides. and a guide roller rotatably mounted upon the pintle.

3. An attachment for vegetable knives comprising a frame havinga topbar. standards supporting the top bar, U-shaped clamps arranged at thebases of the standards, said clamps being open at their rear ends so asto he receivable over the edge of a knife blade. said standards havingslots formed therein. each slot having a serrated side, a pintleextending through the slots and having returned. ends which are adaptedto bear against the serrated sides, and a guide roller rotatably mountedupon the pintle and held in spaced parallel. relation to the cuttingedge of the knife blade.

In testimony whereof I have signed my name to this specification.

JACOB NORTHCUTT.
